[HOT] landuse=residential and routing

Mon Jul 31 18:45:18 UTC 2017

Hi Marco,

The correct drawing of roads should be through the village and not stopping on the residential boundary. In fact there should not be a node connecting road and boundary at all. In the example you showed there is a road running to the south and east bypassing the village. As there is no indication of any clear road through the village itself leads me to believe that those ways leading off the bypass are more likely to be paths that will weave between the buildings and should not be shown as possible vehicle routes.

Hope this helps

Ralph

Thank you for you comments, yes Ethiopia needs to have an OSM restart.
For the last 10 months I was living in SNNPR and was not able to meet a
single OSM contributor.
The infrastructure, unfortunately, makes OSM contributions and even use
very difficult.
Ethiopians would be very interested in getting OSMAnd on their phones,
however, it appears to be a restricted app.

In terms of paths to Ethiopian villages it is indeed the case that the
primary or only transportation route to a population may only be by foot or
donkey traffic on a path.
I think the perception that a path is not important is quite common and is
not true.  Important or significant paths need to be mapped for commerce,
food safety, and potential relief efforts, not only in Ethiopia but in
other parts of Africa and places throughout the world.

The discussion about importance
<http://wiki.openstreetmap.org/wiki/Proposed_Features/Importance> doesn't
seem to have moved forward but could have some value.

At SOTM Africa earlier this month there was quite a bit of discussion on
highway tags, including paths. Based on that discussion I have updated
the Africa
Highway Tagging guide
<http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa> to help clarify
that a road has not only a construction class as well as an economic or
social function.

Doing remote mapping in Nigeria (project #2768), I've a very basic question
(sorry, but I searched a lot in wiki pages and mailing lists, I didn't find
anything about) :

all highways (usually 'unclassified') connecting a village need to be
connected between them, for routing alghoritms?
If so, and the village has no residential highways, have we to draw
"virtual" roads (with highway=residential) inside the village to get the
connection?

Please look at this picture [1] to have an example.

Cheers,
Marco
